Health departments in Iowa and Nebraska today announced that the source of Cyclospora infections in the two states is prepackaged salad mix, but it's not clear if illnesses from the parasite in other states are linked to the same product.
The two states were the first to report Cyclospora illnesses and between them have 221 cases.
In a statement today from the Iowa Department of Public Health (IDPH), Steven Mandernach, chief of the Food and Consumer Safety Bureau of the Iowa Department of Inspections and Appeals (DIA), said epidemiologic and food history interviews with sick patients point to a bagged salad mix containing iceberg and romaine lettuce, carrots, and red cabbage.
The IDPH said the DIA's investigation found that about 80% of the sick patients had been exposed to the same prepackaged salad mix that came from a single source. Mandernach said the salad mix is no longer in Iowa's food supply chain, and he told the state's residents it was safe to continue eating salads.
He said that because of the delay between eating the contaminated food and getting sick, there were no products on shelves to be tested for parasites, and most of the investigation focused on tracing suspected products through the food chain.
The IDPH said it conducted the investigation jointly with the DIA, the State Hygienic Laboratory, local health departments, and public health officials from Nebraska who were investigating a similar outbreak.
Shortly after Iowa announced its findings today, the Nebraska Department of Health and Human Services (NDHHS) announced that prepackaged salad mix was the source of its Cyclospora outbreak, which has sickened 78 people in the state so far.
The NDHHS also said its investigation found that the salad mix, which contained iceberg and romaine lettuce along with carrots and red cabbage, came through national distribution channels, with no indication that locally grown produce was connected to the outbreak.
So far it's not clear if Cyclospora illnesses in other states are linked to the same source. The US Centers for Disease Control and Prevention (CDC) said in an update earlier today that public health authorities are pursuing all leads and that it's not yet clear if cases from all the states are part of the same outbreak.
Christine Mann, a spokeswoman for the Texas Department of State Health Services (TDSHS), told CIDRAP News that so far Texas investigators have not determined a common source of exposure linking the state's Cyclospora illnesses.
Florida epidemiologists also don't have conclusive evidence of a common food item that the state's Cyclospora patients consumed, Ashley Carr, a spokeswoman for the Florida Department of Health (FDH), told CIDRAP News. She added that state health officials are working with the CDC to identify the source of the infections and that interviews are underway to carefully examine the patients' food and ingredient exposures.
So far it's not clear which ingredient was contaminated or if any of the salad components came from imported sources. Cyclospora infections are rare, and past outbreaks have been linked to imported vegetables and fruits. No prepackaged salad products have been recalled as yet.
Today's CDC update said that as of yesterday the agency had received reports of 372 Cyclospora infections from 15 states and New York City. The only new location that was reported is outstate New York, which notified the CDC of a case in a patient who was likely infected in another state.
Some states that had reported cases earlier, such as Florida, Texas, Nebraska, and Wisconsin, reported additional cases, according to the CDC's update.
Florida's outbreak update yesterday included information about the epidemiologic patterns seen among the sick patients. The average age of the patient is 57.5 years, with an age range of 22 to 78. Fourteen patients have been women and 10 were men.
Meanwhile,Texas health officials today announced 11 more cases beyond the CDC's total. Additional new case reported by Nebraska would raise the unofficial outbreak total to 385.
